Music and theology.
A wise man once said, "Liturgy is the music of theology." Is it any surprise therefore, that given the current sorry state of the liturgy, so many "Catholics" subscribed to warped theology?
Lex orandi, lex credendi. The liturgy, I strongly believe, is a reflection of one's belief and understanding of the Faith.
Does Our Lord wear sunglasses and strum electric guitars when He's free? Or does He sit back and listen to the kind of music that He Himself sung with His Mother when He was a little boy in Nazareth?
